National Grid plc: core business model

National Grid plc owns and operates regulated electricity and gas transmission networks primarily in England, Wales, and the Northeastern US. The company transports but does not generate or retail energy, earning returns through regulated asset bases set by Ofgem in the UK and state regulators in the US. This model provides predictable cash flows, with over 90% of earnings from regulated operations as of the half-year report published November 14, 2025, per company filings as of November 14, 2025.

Key to its operations is maintaining high-voltage infrastructure serving 20 million UK customers and 7 million in New York, Massachusetts, and Rhode Island. Investments totaled £4.2 billion in the first half FY26, focused on reliability and renewables integration, underscoring its role in energy security.

Main revenue and product drivers for National Grid plc

Revenue stems from transmission use-of-system charges, approved via multi-year rate plans. In the UK, the RIIO-2 framework through 2026 sets allowed returns on a £50 billion+ asset base. US operations, contributing 40% of profits, benefit from FERC-approved rates, with recent filings seeking £1.5 billion for Northeast grid upgrades, as noted in Reuters as of March 15, 2025.

Product drivers include high-voltage interconnectors like the £1.3 billion Viking Link to Denmark, operational since December 2023, enhancing UK energy imports. Growth areas encompass offshore wind connections and EV grid reinforcements, with £60 billion planned capex through 2030.

Industry trends and competitive position

The global utilities sector faces electrification demands, with US data center growth boosting Northeast transmission needs. National Grid's 25 GW UK capacity and 15 GW US interconnects position it as a leader, per S&P Global ratings report dated January 2026. Competitors like NextEra focus more on generation, giving National Grid a pure-play transmission edge.

Regulatory stability supports its moat, though Ofgem's draft RIIO-3 decisions in July 2025 capped allowed returns at 4.5%, prompting appeals. In the US, Inflation Reduction Act incentives aid clean energy projects.

Why National Grid plc matters for US investors

Listed as an ADR (NGG) on the NYSE, National Grid offers US investors exposure to stable UK utilities plus direct Northeast operations amid rising power demand from AI and manufacturing. Its 5.2% dividend yield as of May 2026 appeals to income seekers, with shares at $72 USD on NYSE per Yahoo Finance data as of May 12, 2026.

Cross-Atlantic diversification mitigates single-market risks, with US assets shielding against sterling volatility. For US portfolios, it hedges against domestic utility rate pressures via global scale.

Conclusion

National Grid plc continues to deliver essential infrastructure services with a focus on regulatory-compliant growth and energy transition projects. Balancing capex ambitions with return caps, the company maintains dividend reliability appealing to long-term holders. US investors gain diversified utility exposure through its NYSE listing and regional operations, though currency and policy risks persist.
